Question

我正在尝试在PowerShell中打开受密码保护的Excel工作表，并输出有关工作表中有多少行的报告。

如果工作表没有密码保护，脚本工作得非常好，但是如果设置了密码，我似乎无法使用PowerShell打开它。

我当前的脚本是

$Report = "S:\Business Support\excel tests\MI Tool - Live.csv"
$path = "S:\Business Support\excel tests"
[Array]$Results = $null
$excelSheets = Get-Childitem -Path $path -Include "MI Tool - Live.xlsm" -Recurse
$excel = New-Object -comobject Excel.Application
$excel.visible = $false
$password = "blablabla"
$updatelinks = 0


foreach($excelSheet in $excelSheets)
{
 $workbook = $excel.Workbooks.Open($excelSheet,$updatelinks,$password)
 $rowCount = $null

  $worksheet = $workbook.sheets.item("Data")
  $rowMax = ($worksheet.usedRange.rows).count
  $rowCount += $rowMax

$Results += New-Object Psobject -Property @{
    "File Name"=$excelSheet.Name
    "Row Count"=$rowCount}
$excelSheet.Name
$workbook.Sheets.count
$rowCount
}
$excel.quit()
Stop-Process -Name EXCEL -Force
$Results | select "File Name","Row Count" | Export-Csv $Report -NoTypeInformation

这是我得到的错误：

Exception calling "Open" with "3" argument(s): "Open method of Workbooks class failed"
At line:3 char:35
+  $workbook = $excel.Workbooks.Open <<<< ($excelSheet,$updatelinks,$password)
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : ComMethodTargetInvocation

You cannot call a method on a null-valued expression.
At line:5 char:37
+   $worksheet = $workbook.sheets.item <<<< ("Data")
    + CategoryInfo          : InvalidOperation: (item:String) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

如果我取出$ password变量，它可以工作，但我必须手动输入密码。

您的Open过载不正确。密码是第5个变量。 Have a look at MSDN to see

表达式.Open（FileName，UpdateLinks，ReadOnly，Format，密码，WriteResPassword，IgnoreReadOnlyRecommended，Origin，Delimiter，Editable，Notify，Converter，AddToMru，Local，CorruptLoad）

所以你需要先填充ReadOnly和Format，我相信。你必须填充这些值。

$excel.Workbooks.open($path,0,0,5,$password)

查看MSDN以了解值在2,3和4位置中的含义。
